An exorcist is a person who performs exorcisms, which are rituals aimed at expelling evil spirits or demons from a person or location. The practice of exorcism has a long history in many cultures and religions around the world. In Christianity, exorcism is performed by authorized clergy members, usually priests or bishops, who are trained in the practice of exorcism and authorized by the church to perform the ritual. While the practice of exorcism remains controversial and is not recognized by all religious traditions, many people continue to seek out the help of exorcists in order to rid themselves or their loved ones of evil spirits or demonic possession.
